To It whom it may concern.-

Be it known that I, JOHN STUBBE, a rcsident of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Machines for Applying Plates or Barbs to FenceWVire; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view of my improved wire-barbing machine.

Fig. 11 is a view showing the movement of the pin 2 as it centers the tablet on the table. Fig. 12 is an end view of the bar 12 and the pin n.

Like letters of reference indicate like parts wherever they occur.

My improvement is designed,primarily, for the purpose of attaching warni rig-plates, sheet metal barbs, or other similar articles to strands of wire for wire fencing. Vith necessary modifications it may also be used for analogous purposes; but for convenience sake I shall describe it with reference to the application of those warningtablets for which I have already obtained Letters Patent of the United States, No. 287,337, of October 23, 1883.

In my improved machine the wire is fed in two strands, a (E, from spools a, which are mounted upon the bed-plate a, through feedrollers b b,along guide-wheels m on oscillating arms a a, and thence between a reciprocating table, 0, and oscillating rod 19, the latter situ- Fig. 9

frame of the spinner, and the twisting of the wires is therefore done along the course of the wires from their bearing on the reel to the ends of the oscillating lingers a 11., where they are confined between the guidcwvhcels if. The rotation of the spinner and the twisting op eration are continuous. The reel 0 is journaled within the spinner f at right angles to its axis, and is actuated by uitable gearing, so that as the feed-rollers Z) I) feed the strands into the machine the reel may gather and wind them in readiness for transportation and sale. The reel also serves to keep the wires from sagging during their passage through the machine. An intermittentmotion of the feedrollers b b checks the passage of the strands during the process of adjusting the tablets. and simultaneously stops the rotation of the reel 6. A wire-distributor, consisting of a movable sleeve, g, is mounted on a right-andleft threaded shaft, h, which extends transversely across the spinner. The wire passes between radial forks on the sleeve, and thus turns it and causes it to move from one side of the spinner to the other, thereby causing the twisted wire to be distributed regularly upon the reel. Power is applied by means of a suitable belt-wheel, i, which connects with the rotary spinner f, and thence by intermediate gearing or belting to the other parts of the machine.

I will now proceed to describe my improvement in detail.

The feed-rollers b b are revolved by means of a shaft, j, connected by a belt, b withga gearing device, k, which is so arranged as to stop the motion of the feed-rollers for a time at certain regular intervals, and the pe too the level of the strand-wires.

device k more fully hereinafter. The feedrollers b b are preferably arranged in two adjacent pairs, one member of each pair being situate directly over the other, and the upper rollers, b, movably journaled in slots b, so that their faces may be movable toward the lower pair and may feed the interposed strand-wires forward by friction. The spoolsaa are loosely mounted upon spindles a, so that when exhausted of wire they may be removed and full spools substituted, the upper feed-rollers, b, being raised in the slot b", so as to permit insertion of the wires of the fresh spools. The upper feed-rollers, b, are pressed upon the a lower rollers, b, preferably by means of two parallel horizontal lever-arms, ZZ', connectedat their inner extremities near the feed-rollers by a vertical rod, Z, the upper lever-arm, Z, pivotally connected to said rod, and the lower arm, Z, attached to the frame of the machine. A rope or chain, 1, is fastened to to the lower arm, Z, and passing over a sheave, Z, on the free end of the arm Z is attached to a weight, Z The effect of the weight is to depress the lever-arm Z, which bears upon the axis of the upper feed-rollers, b, and to press said rollers down toward the faces of the lower feed-rollers, b. It is obvious that as these rollers'grasp the strand-wires between their peripheries and revolve they will feed the wires forward from the spools a to the other parts of the machine. From the feed-rollers b b the strand-wirespass along grooved guidewheels m m m mounted on the oscillating horizontal arms a nthat is to say, they extend along the grooves on the'inner faces of the guide-wheels m, which are situate at the lree ends of the arms a a, and along the outer faces of the grooved wheels m, next adjacent thereto. The course of the wires is thence above the surface of the table 0, which is so arranged as to be capable of a vertically-reciprocating motion up to and downward from One of the functions of this table is to act asa lifting and adjusting device for the fence-tablet. The tablet is placed on the table when it is in its lowest position, and the rise of the table lifts the tablet into place between the then separated strands.

Above the table 0 is a centering-pin, a, attached to-the extremity of the oscillating pivoted harp, movable reciprocally with relation to the motion of the table 0, so that as the table raises the placed barb to the level of and between the wires a. a the centering-pin may descend and engage the tablet there. The result is that the tablet is clamped firmly between the reciprocating table and the centering-pin n in the proper position, so that when the wires are brought together by action of the arms a n they may be forced exactly into the notches-made in the tablet for that purpose.

In order that the operator may easily adjust the tablet on the table with its notches open toward the strand-wires, the surface of the table may be provided with parallel guideribs o',upon which the tablet is set. If the latter be set a little out of alignment, the clamping of the pin a thereon will cant or turn it upon the ribs 0 to the proper position. When the tablet is clamped between the table 0 and the end of the harp, as just described, the feed of the wires is caused to stop by automatically checking the revolution of the fecd-rollers b b, and the revolution of the spinnerf twists the wires toward the tablet. (See Fig. 1.) Before the twist has quite reached the tablet the free ends of the oscillating fingers n n approach, bringing the guide-wheels m together and forcing the strand-wires a or into the notches in the sides of the tablet. the strands have been twisted up to the tablet, the table 0 and the rod p,which carries the centering-pin 11?, separate, and the feed-rollers b b begin at thesamemoment,orimmediatelyafterward, to revolve, so as to feed the wire forward.

and to allow the twisted strands to be wound upon the reel 6. The tablet will then be free, and will move with its inclosing strand-wires away from the table 0 and toward the reel. During this motion the continuous rotation of the spinnerf will twist together so much of the strand-wires as lies between the tablet and the ends of the closed fingers na,and the same twisting action is continued after the tablet has ceased advancing. The object of closing the fingers an before the separation of the table 0 and bar 9 is to press the strand-wires securely into the notches of the tablet,-and by confining the wires in these notches to support the tablet when it has been released from the centering-pin a and table 0. supported a secure twist is produced on both sides of the tablet. When the wire has nearly passed through the distance desired between the tablets, the fingers n a separate and spread the wire-strands apart, the feed motion immediately afterward stops, and the operator inserts a tablet upon the table 0. The reciprocating table 0 then rises and lifts the tablet into position between the wires, the centeringpin a closes upon and adjusts it, and the operation of twisting the wire goes on as before. The action of the tableo and bar is a clamping action, being designed both to hold and adjust the tablet. I shall so refer to it inthe claims. When the oscillating fingers a a open, as I have described, the resulting effect is to force the twist of the strands up to the tablet, and thereby to render the connection between the strands and the tablet much more secure. The operation of the fingers n a is illustrated in detail in Figs. 1 and 3. The fingers being pivoted at points 9, preferably about midway of their length, are provided at their' extremities with lateral armsr r, the arm "1" 'of the right finger extending to the left and the arm 1- of the other finger to the right. The arms 1 r are pivotally attached to the extremities of the fingers a a, and at their other ends to the upper extremities of upright bars 8. The upright bars 8 are also pivotally connected at s s and a by diagonal rods t to Being thus an upright sliding bar, a, suitably mounted in grooves or standards on the frame of the machine between said upright oscillating bars. The diagonal rods t are pivoted both to the oscillating bars 3 and to the sliding bar it, the bars 8 being pivoted at 3. An eccentric earn, 12, is suitably journaled, so that its periphery may bear upon a pin, w, on the sliding bar a, and by revolution against the same may impart a vertical reciprocating motion to the sliding bar. The upward motion is accomplished by the ordinary operation of an eccentrically pivoted disk, and to secure downward motion there is a groove, 5, across the surface of the cam, one end, z, of which is at the greatest distance from the axis of the cam and the other, z' at the nearest point thereto. \Vhen the cam has raised the pin to and sliding bare to the highest point, the pin enters the end 2 of the groove z and is forced down by the outer side of the groove until it emerges from the end From this point a portion of the periphery of the cam is concentric with the axis, so that the sliding bar is kept at its lowest position until the eccentric portion of the periphery of the cam again reaches the pin 20. The effect of the intermittent reciprocating motion of the sliding bar a is to alternately raise and lower the point where itis joined to the diagonal arms t, and to spread and bring together the free ends of the upright oscillating bars 8. These communicate a corresponding motion to the pivoted fingers n a, so that when the bar a is rising the fingers an open,and they close as the passage of the pin 10 through the groove 2' brings down the bar, and remain closed until the pin again meets the eccentric portion of the periphery of the cam.

The reciprocal vertical movement of the table 0 and of the bar 1), which carries the centering-pin a" and guide blades or teeth 0, are secured as follows: The horizontal bar 9 is pivoted transversely to the frame of the machine upon an upright support, 2, and is pivoted at one end to the extremity of an upright rod, 3, the other end of which is pivoted to an oscillating rod, 4. The rod 4 is pivoted at one end to an upright sliding bar, 6, which supports the taLle 0, and at the other end either to the frame a, or preferably, for convenience sake, to the axis of one of the gear-wheels 5 of the machinery. The table 0 is mounted upon a vertical reciprocating bar, 6, operated by an eccentric cam, 8, keyed on the shaft 30, bearing upon a pin, 7, on the same, and operating in a mannersimilar to that described with reference to the sliding bar a in Fig. 3. A portion, 10, of the highest part of the periphery of the cam 8 is concentric, as is also a larger part of the lowest portion, 9, of the same, so that when the sliding bar 6 and table 0 are at their highest point, and the tablet is clamped between the table and the centering-pin if, they may remain in that position for a time, and when the pin 7 is at its lowest point, and the table and centering-pin are separated so as to release the tablct and permit free passage of the wires, they may remain in that position for a still longer time. The rising of the bar 6 also elevates the end of the rod 4, pivoted thereto, and this raises the rod 3 and depresses the pin n at the free end of the bar 1), so that the centering-pin and reciprocating table may respect ively approach and recede simultaneously. If desired, only one of these parts 1) and 0 may be made movable, and the other stationary; but I prefer the construction shown in the drawings, since it holds the fence-tablets more securely and gives greater room for their insertion. The alternate motions of the oscillating arms an, the table 0 and centering-pin or, and the feed-rollers b 1), whereby the arms approach before the table and centering-pin separate, and the feed-rollers stop before the table and ceuteringpin meet upon the tablet, are preferably secured by driving them from the same power-shaft, 30. and by suitable adjustment of their auxiliary gearing, as will be readily understood. The twisted wire passes from the oscillating rod and table 0, where the fence-tablet is attached, through a hollow cylindrical shaft, (1, which is the journalshaft of the rotary spinnerf, within which the reel 6 is journaled. The motion of the spinnerf is continuous, and it is preferably belted directly to the main belt-wheel z, and imparts motion by suitable belting, g, to the other parts of the machine.

The manner in which the reel 0 is actuated is as follows: A horizontal shaft, 14, journaled upon the bed-plate of the machine, passes loosely through the frame of the spinnerf and the belt-wheel i, and is provided at its rear extremity with a friction-wheel, 13, bearing upon the face of which are friction rods or clutches 12, or other suitable device for retarding the revolution of the wheel 13. The other end of the shaft 14, within the circumference of the spinner, is provided with a miter-wheel, 15, which gears into a similar miter-wheel or pinion, l6, journaled to the side of the spinner-frame. The pinion 16 is connected by sni. able gear-wheels, 11, to the axis 6 c of the reel 6. The wheel 13 being held stationary by the action of the friction-brake 12, revolution of the spin ner f will carry the beveled surface of the miter-wheel 16 around the surface of the stationary miter-wheel 15, and will impart a rotary motion to the wheel 16 and its shaft, as will be readily understood. The rotary motion of the shaft of the wheel 16 also rotates the gear-wheels 11, and through them revolves the reel 0 upon its axis 0 c and winds the twisted strand-wires thereon.

I have mentioned the fact that when the motion of the feed-rollers b b is checked,so as to allow the barbed plate to be adjusted between the wires and to be held in position while the strand-wires are twisted about it, the revolution of the reel 6 is also stopped, since otherwise the strandwires would be broken. This stoppage of the reel is caused by the action of the brake 12 upon the wheel 13. Thus when the feed-rollers b b have stopped, the friction of their faces holds the strand-wires a a and opposes resistance to the turning of the reel 6 and to the rotation of the miter-wheel 16. This friction would break the wires were it not that when the strain has reached a certain point within the tensile limits of the strand-wires the wheel 13 overcomes the resistance of the brake 12 and turns with the miter-wheel 15 upon its axis. When this happens, it is obvious that the miter-wheel 16 will turn about the face of the wheel 15 without the resulting rotation which I have described, and that consequently the reel 6 will also remain at rest. As soon as the rollers b I) begin again to feed the strandwires forward, the strain upon the reel 6 is released, the wheel 13 and pinion 15 come to rest,and the reel recommences to revolvefreely. To produce this result it is of course necessary to properly adjust the-friction upon the wheel 13,- so that it shall not exceed the desired limit.

The advantages of this device are great. It not only serves the purpose I have described, but also serves to regulate the winding action of the reel. Thus if the reel 6 does not move fast enough to wind the twisted wires as fed from the feed-rollers b b,the resistance necessary to stop the reel will not occur until after the feed-rollers have stopped, and in the meanwhile the wire is wound tightly upon the reel. On the other hand, if the reel revolves too rapidly, so as to produce a strain upon the wires, thisstrain will stop the reel and allow it to accommodate itself to the motion of the feed-rollers. It is obvious that this change in relative motion will occur continually in practice, since when the reel is nearly full of wire its winding circumference increases, so that one revolution on its axis will wind far more wire than if'it were empty.

The gearing device 7c, which causes the intermittent motion of the feed-rollers b b, is illustrated in detail in Figs. 6, 7, 8, and 9. A plate or disk, B, is keyed to a miter-wheel, L, or other suitable gearing, which meshes with the miter-wheel 33, which is keyed to the shaft 30 and is adapted to impart a continuous rotation to the disk. The disk Bis provided on its inner face, near the circumference, with a lug or projection, G, and is fitted within a fixed drum or casing, D, which has a central aperture, D, for the entrance of a cylindrical shaft, A, which passes through the miter-wheel L,.the disk B, and drum D, and turns loosely within the same.

Between the disk B and the'base of the.

drum D are parallel plates D D, attached to or integral with an annular collar, D,'which is keyed to the shaft A by key V, or they may be keyed directly to the'shaft, as preferred. These plates are. so arranged with reference to each other as to provide radial ways or slots E E, within which sliding dogs F F are so mounted as to project on both sides of the plates, and to be capable of motion in said ways toward and away from the center of the drum. The plates D and D are placed between a collar, B, on the disk B, and a stationary cam, G, which is secured to the under side of the drum and encircles the collar D. The periphery of the cam G is circular, except that it has a depression or recess, H, which isthe counterpart of a stationary cam, I, arranged on the drum D opposite thereto. The sliding dogs F F preferably bear on one side of the plates D and D against the face of the disk B, and on the other side against the un-' der side of the drum D. The inner extremity of each of the dogs also bears against the periphery of the cam-collar G. Opposite the stationary'cam I there is a lateral recess, J, in the side of the drum D, within which recess is pivoted an arm or catch, K, having a notch or recess, J, directly'opposite the highest point of the stationary cam I. The side of the arm K lies within the path of revolution of the lug O on the disk B, so that the lug C may strike it and force it back into the recess J. A suitable spring, K is secured to the arm K, so as to press it in the recess toward the central part of the drum D. The arm is, however, confined within the recess by contact with the sides of the drum, as at K. Theannular collar D to which the plates D D are attached, is keyed to the shaft A, which is connected by abelt,b on the wheels and j to the feed-rollers b b. The function of the plates D and D is to act as lever-arms for the shaft A, so that as they revolve around the circumference of the drum D they may also turn the shaft A. When they are at rest, the shaft remains at rest also. The feed-rollers b I) being connected with and actuated by this shaft A, it is obvious that they will revolve with the plates D D and will partake exactly of their motion.

Thus constructed, the operation of this part of my improvement is as follows: The plates D and D being in the position shown in Fig. 8-namely, with one of the sliding dogs, F, at the end of the slot E, and in and confined by the notch on the spring-catch K, and the dog F opposite the stationary cam I-the continuous revolution of the gear-wheelL will carry the rotary disk B with it until the lug G on the disk strikes the side of the pivoted arm K. The lug G will then push the arm K back into the recess J until the sliding dog F is released from the notch J, and as the dog is at the endof the slot E and in the path 0 of the lug the lug G will engage it, and will carry it and the plates D and D between which it is mounted, around the circumference of the cam G. When, however, the dog F has reached the cam I on the drum, the inclination of its face forces the dog along the ways E into the opposite recess, H, of the cam G and out of the path 0 of the lug O. The lug O is thereby disengaged from the dog F, andis left free to pass under or by the stationary cam I, and to continue its revolution without moving the plates D and D or the shaft A. At the same time that the dog F is pushed in the ways E into the recess H on the cam G the opposite dog, F, having engaged and pushed back the spring-arm K, slips into the notch J. The arm K then springs back into its first position, and by holding the dog F prevents the plates D and D from revolving. The object of catching the dog within the notch 11 is to immediately check the revolution of the plates D and D and of the shaft A, and thus secure accuracy in the motion of the feed-rollers. \Vhen the lug 0 again reaches the pivoted arm K and engages the dog F, its revolution causes the other dog, F, to slide in the ways E, out of the recess H, and to move around the periphery of the cam-collar G and in the path of the lug O, as before described. By these means it is clear that the plates D and D and the shaft A revolve only with every alternate semi-revolution of the disk B, and remain stationary during the other semi-revolution, and as the feedrollers b b are actuated by the shaft A they, too, partake of its intermittent motion and alternately revolve and re main at rest-that is to say, that when the projection or lug O is moving from the point J to the point I it is turning the shaft by means of one of the dogs and the plates D and D and that at I it is disconnected from the shaft by the inward movement of the dog in the ways E, and moves from I to J without turning the shaft.

By reference to the drawings it will be seen that I have shown the dogs F F as of an L shape, the shank extending beyond one side of the plates D and D, and the base thereof projecting beyond the other side, and that the spring-arm K is placed at one side of these plates and the cam I on the other side. I consider this the preferable arrangement, but do not desire to limit my claims thereto.

If preferred, any other suitable devicesuch as mutilated cog-wheels and the like-may be substituted for the intermittent gearing I have just described; but I prefer the latter on ac count of its simplicity and extreme accuracy of adjustment. It is not liable toget out of order, and is especially applicable to the production of intermittent motion in wire-barbing machines of like nature with the one which I have described in this specification, where it is desirable to produce a sudden intermittent stoppage of the machinery without jar or recoil. This object is attained by the action of the notched spring-catch K upon the dogs F in an easy and regular way, and is of beneficial effect in lessening the wear and tear on the machinery and in the prevention of the destructive accidents which are likely to arise from use of mutilated cogs. On the spinner shaft d is a belt-wheel, g. which is connected by a belt with the wheel 34 on the shaft 31, which shaft, by means of a belt and wheels 35 and 36, imparts motion to the shaft 30, upon which shaft are mounted the cam S and miterwheel 33, so that the motion of each part is derived from the same source.

I do not wish to claim in this application the mechanism for producing intermittent motion, which is herein described and is shown in Figs. 6, 7, 8, and 9 of the drawings, because I have made it the subj eet-matter of a separate application for Letters Patent of the United States, filed by me on the 8th day of January, 1885, and numbered 152,249.
